4. In shearing and clipping mechanism, the combination ot' a cuttingplate suitably mounted for movementin one plane and having aslotdirected transversely of the aforesaid plane, and a lever engaging saidslot and mounted for movementin a plane transverse of saidfirst-mentioned plane and said slot.

5. In shearing and clipping mechanism, the combination of a cuttingplate suitably mounted for movement in one plane, and having a slotdirected transversely of the aforesaid plane, and a lever havingsurfaces substantially parallel to and engaging the walls of said slot,said lever mounted for movement in a plane transverse of saidrst-mentioned plane and said slot.

6. In shearing and clipping mechanism, the combination of acutting-plate mounted to move in one plane, consisting of a body portionhaving cutting-teeth and an extension substantially perpendicular tosaid body portion, said extension provided with a slot inclined to saidbody portion; and a lever engaging said slot and mounted to oscillate ina plane substantially perpendicular to said plane of movement of saidcutting-plate.

7. In shearing and clipping mechanism, the combination ot' areciprocatable cutting-plate consisting of a body portion havingcuttingteeth and an extension substantially perpendicular to said bodyportion and substantially parallel to the line of reciprocation of saidcutting-plate, said extension provided with a slot inclined to said lineof reciprocationv of said cutting-plate; and a lever engaging said slotand mounted to oscillate in a plane transverse of said .line ofreciprocation of said cutting-plate to reciprocate said cutting-plate.

8. In shearing and clipping mechanism the combination of a frame havinga handle extending therefrom, a cutting-plate mounted to reciprocateupon said frame in a direction transverse of said handle, a leverpivoted upon said frame to oscillate in a plane transverse ot' the lineof reciprocation of said cutting-plate, said lever having a handleportion disposed beneath the said handle of said frame; and an inclinedslot and lug connection directly connecting said lever and saidcutting-plate, whereby said cutting-plate is reciprocated by theoscillation of said lever.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
